摘要
计算了月球赤纬角最大和最小时地球的潮汐形变值.结果表明,当赤纬角最大时月球引潮力所引起的地球表面积和地壳容积变化量是赤纬角最小时所引起的相应变化量的2.3倍.因此,当月球赤纬角最大时地球大量放气,而月球赤纬角最小时气候干旱,中国大陆出现旱灾.用地球自转速度变化周期和地震周期对上述结论进行了论证.
As shown from calculation,the change of the earth's surface area and the crust's volume caused by the moon's maximum declination is 2.3 times as big as that caused by its minimum.This can well account for the gas release from the earth when the declination is at its maximum and for the corresponding droughts in China when at its minimum.This mechanism is also confirmed by both the periodical variation of the earth's rotation and the periodical occurrence of earthquakes.
